*1 If the red lamp continues to blink even after the charger
has been attached, check to confi rm that the battery has
been fully inserted.
*2 Although charging will start once the battery has cooled
down even when left in situ, the best practice is to
remove the battery and allow it to cool down in a shaded,
well-ventilated location before charging.
*3
○ Fully insert the battery.
○ Check to confi rm that no foreign matter is stuck to the
battery mount or terminals.
<If charging takes a long time>
○ Charging will take longer at extremely low ambient
temperatures. Charge the battery in a warm location
(such as indoors).
○ Do not block the air vent. Otherwise the interior will
overheat, reducing the charger's performance.
○ If the cooling fan is not operating, contact a HiKOKI
Authorized Service Center for repairs.
